FALL RIVER, Mass. (AP) â€” Aaron Hernandez’s attorneys asked a judge on Tuesday to approve their subpoena to the New England Patriots for the team’s medical, psychological and other records on the former player.

Hernandez has pleaded not guilty to first-degree murder in the June 2013 shooting death of Odin Lloyd, whose body was found in North Attleboro near Hernandez’s home.

On Monday, a Bristol Superior Court judge set a July deadline for the team to respond to the defense’s earlier requests for the 2010-2013 records. But in a motion filed Tuesday, Hernandez’s attorneys said the records are potentially relevant to his circumstances and state of mind, and asked to have them within 30 days.

The motion said the request “is not intended as a general ‘fishing’ expedition” but is essential to preparing for his trial, which may begin in October.

Hernandez, a tight end, was drafted by the Patriots out of the University of Florida in 2010. The team released him in June 2013 hours after he was arrested in the slaying of Lloyd, a semi-professional football player who was dating the sister of Hernandez’s girlfriend.

Hernandez also pleaded not guilty last month in a separate case accusing him of killing two men in Boston in July 2012, about a month before he signed a five-year, $40 million contract extension.
